Technical field
The utility model relates to one and fells and transports coal all-in-one, and what particularly a kind of advance distance of continuously lateral coal cutting fortune coal was long fells and transports coal all-in-one.
Background technology
Cut continuous coal cutting in side fells and transports coal all-in-one, coal all-in-one is felled and transported disclosed in China Patent Publication No. CN103742138A, and there is disclosed in CN104234712A top coal recovery device fell and transport coal all-in-one etc., its solve existing girdle or relatively thin in the critical facility of thick level or flat seam mechanization manless working face, coal mining main frame drives drive chain horizontal cyclic to move by drive sprocket, the mode utilizing the carrier bar connected at drive chain to arrange coal cutting teeth realizes mining, and formed by carrier bar and fuselage and transport coal crossheading, thus form the integrative-structure coal mining main frame felling and transporting coal one, fuselage is used as load bearing component and the guiding parts of carrier bar, fuselage is formed by connecting by multiple case unit, connected by Push-fit between each case unit, fuselage height and coal mining amplitude correlation, coal mining amplitude sets according to coal seam thickness usually, fuselage is advanced by the propelling cylinder between itself and hydraulic prop system.In coal mining process, the coal seam of the supporting roof front end of hydraulic prop system is adopted sky partial width and can not be exceeded the requirement of the coal mining distance of face roof under control, therefore, advance once for the propelling cylinder stroke of circulation of once mining restricts by the coal mining distance of face roof under control with hydraulic prop system, this coal mining distance of face roof under control is determined by coal geology situation and coal mining relevant safety regulations.Between the hydraulic prop being connected to hydraulic prop system front end due to the existing propelling cylinder felling and transporting coal all-in-one and fuselage, therefore, the pushing distance of each circulation of mining is short, and support system moves frequently, and coal mining efficiency is low, and energy consumption is high.For this reason, need to improve felling and transporting coal all-in-one, to improve the pushing distance of single coal mining circulation.
Summary of the invention
The utility model object be to provide a kind of advance distance long fell and transport coal all-in-one, it increases propelling hydraulic cylinder stroke by mode propelling hydraulic cylinder cylinder body bottom being extended to hydraulic prop rear, to realize the object strengthening single coal mining circulation coal-winning machine main frame and support system advance distance, reduce support system and pass frequency, improve coal mining efficiency, reduce energy consumption.
For achieving the above object, the utility model adopts following technical scheme.
What a kind of advance distance was long fells and transports coal all-in-one, comprise and fell and transport coal main frame and hydraulic prop system, the fuselage felling and transporting coal main frame is connected to form by multiple case unit, hydraulic prop system is connected with the fuselage felling and transporting coal main frame by propelling hydraulic cylinder, hydraulic prop system comprises supporting roof, supporting roof front and back end is respectively equipped with a hydraulic prop, and the cylinder body bottom of described propelling hydraulic cylinder is positioned at the hydraulic prop rear of supporting roof front end.
Adopt the utility model of preceding solution, the cylinder body bottom due to propelling hydraulic cylinder is positioned at the hydraulic prop rear of supporting roof front end.Therefore, effectively can increase hydraulic cylinder travel, thus guarantee under the prerequisite setting the distance of face roof under control, effectively can increase the coal mining main frame advance distance of single coal mining circulation and the pushing distance of support system.Effectively can reduce the passing frequency of support system, improve coal mining efficiency and reduce energy consumption, improving energy utilization rate.
Preferably, described propelling hydraulic cylinder is hinged on the hydraulic prop of supporting roof front end by the optional position at front end to the middle part of cylinder body.Utilize the main body of hydraulic prop that propelling hydraulic cylinder is set, make its structure simple.
Preferably, described supporting roof front end is provided with two hydraulic props, is connected with U-lag or rectangular channel framework between two hydraulic props; Described propelling hydraulic cylinder is hinged on the trench bottom of U-lag or rectangular channel framework.Utilize synchronization-moving two front end hydraulic props that propelling hydraulic cylinder is set, make its setting position more flexible, and by U-lag or rectangular channel framework are set different slots at the bottom of the degree of depth guarantee propelling stroke requirement.
Preferred further, described supporting roof rear and front end is respectively equipped with two hydraulic props, is connected with link component between two hydraulic props of supporting roof rear end; Described propelling hydraulic cylinder is hinged in the middle part of link component.Utilize synchronization-moving two rear end hydraulic props to arrange propelling hydraulic cylinder and can use up limits increase propelling stroke, and do not need connecting elements to be arranged to U-lag or rectangular groove structure, its structure adds list more.
The beneficial effects of the utility model are, strengthen single coal mining circulation coal-winning machine main frame and support system advance distance, reduce support system and pass frequency, improve coal mining efficiency, reduce energy consumption.
